The Digital Output Driver X1-IS-DO-01 module is suitable for energizing safety related circuits, up to SIL 3 level, for high risk industries. It can drive solenoid valves, visual or audible alarms to alert a plant operator, or other process control devices in Hazardous Area from control signals located in Safe Area. They can also be used as switchable supplies to power measuring or process control equipments. On the field side, the three most widespread Intrinsic Safety valve family parameters are supported. On the system side, a wide compatibility towards different DCS/PLC is guaranteed: driving pulse testing is permitted by a dedicated internal circuit, which prevents spurious activations and LED flickering, while offering an acceptable resistance to the DO Card. To ease maintenance operations, field devices can be disconnected through a two-position insertion/extraction mechanism. This product requires a dedicated Termination Board.
